Locking Rear Axle (If Equipped)
If your vehicle has this feature, your locking rear axle
can give you additional traction on snow, mud, ice, sand
or gravel. It works like a standard axle most of the time,
but when one of the rear wheels has no traction and the
other does, this feature will allow the wheel with
traction to move the vehicle.

Tilt Wheel (If Equipped)
A tilt wheel allows you to adjust the steering wheel
before you drive. You can raise it to the highest level
to give your legs more room when you exit and enter
your vehicle.
To tilt the wheel, hold the steering wheel and pull the
lever toward you. Move the steering wheel to a
comfortable level, then release the lever to lock the
wheel in place.
Do not adjust the steering wheel while driving.
The tilt lever is located
on the driver's side of the
steering column, under the
turn signal lever.
